The purpose of this project is to expose the process to be carried out during the internship work at Fundación Ayuda por Colombia, with the development of a training process for singing and the creation of a children's choir, proposing a methodology based on theoretical resources and practical that have already been used previously for the same purpose. In this process, a series of steps can be evidenced, ranging from how to get properly involved with children in vulnerable situations, to knowledge of the human body, physical exercises, creation and assembly of a musical repertoire for singing for two voices. An important point of this project is to encourage the creation of pedagogical strategies counting on referents that have produced results, that contribute to the adequate advancement and progress of the students to achieve the proposed goals. This is due to the fact that both the pedagogical work and the learning can vary depending on the age of the student and their social context, thus the training process can be modified on the fly with solid and effective bases to have the best possible results.
